SCREEN FOR DOORS AND WINDOWS.

Specification of Letters Patent.

Application filed October 31, 1912. Serial No. 728,947.

To all 207mm it may concern:

Be it known that I, Cnannns E. MAr'rrsoN, a citizen of the UnitedStates, residing at Lake Charles, in the parish of Calcasieu and Stateof Louisiana, have invented a new and useful Screen for Doors andindows, of which the following is a specification.

This invention relates to screens for doors and windows, its principalobject being to provide an all metal device of this character which canbe used in the same manner an ordinary window or door screen and whichis provided with means whereby the entrance of unauthorized personsthrough doors or windows is prevented.

Another object is to provide a screen of this character which iscomparatively simple in construction and which is attractive inappearance.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred forms of the invention havebeen shown.

In said drawings :Figure 1 is an elevation of a portion of a screen doorembodying the present improvements. Fig. 2 is a section on line ABFig. 1. Fig. 3 is a view partly in section and partly in elevationshowing one of the cross bars and the adjacent parts of the sides of thescreen frame. Fig. 4 is a view similar to Fig. 1 but showing a slightlymodified form of structure. Fig. 5 is a section on line 0-1) Fig. 4.

Referring to the .figures by characters of reference 1 designates thesides of a screen, the same being made of pipe sections connected byT-joints 2. The top and bottom rails 3 of the screen frame are formed oflengths of pipe and the ends of these top and bottom rails are connectedto the side rails by means of elbows 4, these elbows being angular asshown in Fig. 1. Each elbow has a flat outer face but a round threadedinterior. It will be noted that the ends of the sides 1 and of the topand bottom rails 3 are reduced in diameter to form screw threadednipples sothat, when the nipples are in engagement with the elbows 4,the outermost surfaces of the rails are disposed flush with thecorresponding surfaces of the elbows and it is thus possible for theframe to rest fiat upon a supporting structure and to fit snugly againstthe sides of a door or window frame. The T-joints 2 are engaged by thethreaded ends of cross bars 5, each bar being preferably tubular andhaving its ends provided with right and left hand threads respectively.These bars are preferably spaced about six inches apart so as thus toconstitute guards to prevent persons from passing through the screenframe after cutting the wire fabric therefrom. This wire fabric has beenindicated at 6 and its edge portions are attached to the frame of thescreen by means of metal clamping strips 7 which are attached to thesides, top and bottom of the frame by means of screws 8 or the like. Itis preferred to have each side and the top and bottom of 7 he frameprovided with a flat face such as shown at 9 in Fig. 2 nd on which theedge portions of the screenfabric rest. It will be apparent that withthis construction the screen fabric 6 can be removed whenever desiredand a new one substituted therefor. The frame of the screen ispractically indestructible and, when once secured in position, will actas an efficient guard to prevent persons from entering the buildingthrough the doors or windows in which the screens are secured.

Instead of forming the top and bottom rails of the screen of tubes, asshown in Fig. 1, bars 10 may be interposed between the ends of the sides11 of the screen frame as shown in Fig. 4, the ends of the bars beingconcaved, as shown at 12 in Fig. 5, so as to straddle the sides of thescreen frame. Furthermore, if desired, dowels 13 or the like may bearranged in the concaved ends 12 so as to engage the sides 11. Byutilizing bars such as described, the ends of the sides can be cut offsquare and there willthus be no difficulty in providing a frame whichwill be perfectly rectangular. The cross bars 1 1 which correspond tothe bars 5, will of course hold the sides 11 properly assembled withrelation to the top and bottom rails 10.

Instead of forming the side rails of sections of pipe and ofT-couplings, each side can be formed in a single piece of the contourshown in Fig. 5.

What is claimed is z-- A screen including a frame made upoidetachabiyconnected tubular side members, top and. bottom rails connected to theends thereof, each of said members and rails having a flat fabricengaging surface, a screen fabric mounted at its edges on said flatsurfaces, means for clamping the fabric upon said surfaces, there beinginwardly extending tubular portions upon certain of the tubular sidemembers, said portions being lapped by the screen fabric, and cross barsas my own, I have hereto affixed my signature in the presence of twoWitnesses.
